[Prior Art] The general structure of a conventional inspection device for a liquid crystal panel is as shown in Figs. 3 and 4, and the probe 2 of the probe block (1) 151 is abutted. The tester main body 7 is connected to the flexible substrate 5 of the probe 2 via the probe 2 at one end of the array glass substrate 3 for the liquid crystal panel, and the other end of the flexible substrate 5 is connected. The board 6 is connected to read the signal from the terminal material pattern 4 to check the short-circuit state, the open state, the TFT characteristics, and the pixel characteristics of the terminal conductive pattern 4. At this time, the probe block 1 is provided with abutting The plurality of probes 2 for the terminal conductive patterns 4 of the array glass substrate 3 for a liquid crystal panel are tested, and a plurality of probe block bodies are disposed in accordance with the number of blocks of the terminal conductive patterns 4 (see FIG. 4). In each of the plurality of probe blocks, the probe 2 and the flexible substrate 5' probe 2 are respectively connected to the odd-numbered and even-numbered wirings of the terminal conductive pattern 4, and the flexibility is obtained. The substrate 5 is electrically connected - the odd-numbered corresponding flexible base & 5a and pure The flexible substrate 5b is formed. Further, the other end of the flexible substrate 5 is connected to the other end of each of the odd-numbered flexible substrate 5a and the even-numbered corresponding flexible substrate 5b, and is provided with an address conversion function. The odd-numbered corresponding address portion 仏 and the even-numbered 315762 6 1325499 corresponding to the address portion 6b in the board 6 are such that each probe block 1 is connected to the mating plate 6. The tester body 7 is provided with a plurality of probe pins (probe pin) P (for example, 1200 to 2000) 'This probe pin P is abutted against the same number of land L disposed on the mating plate 6 to obtain electricity with the mating plate 6. In addition, the component symbol 21 in Fig. 3 supports the support frame of the probe block 1. When the performance of the TFT array substrate constituting the liquid crystal panel is checked, TAB (Tape Automated Bonding) and printing are automatically combined in the combined roll ▼ In a pre-process of a large-scale integrated circuit LSI (Large Scale Integration) for driving a panel to be lighted, a circuit board PCB (assembled printed circuit board) is applied to a pixel signal terminal conductive pattern of the array glass substrate 3 for a liquid crystal panel. 4 lines for each inspection panel This test uses the same number of probes 2 as the number of conductive patterns for the pixel signal terminals. Therefore, when the V-electric pattern 4 for the terminal of the array glass substrate 3 for a liquid crystal panel is disposed, a plurality of the plurality of terminals are mounted. Probe block 1 of probe 2. Moreover, the pixel inspection signal is distributed to the odd number pixel terminal and the even number pixel terminal during the inspection. This probe block has been disclosed in the probe block shown in Fig. 5. The body 1 (for example, Japanese Patent Laid-Open No. Hei 8-222299 (page 3, page 4, (10))) is not disclosed. The general structure of the probe block is supported by (4) plate-shaped insulation The needle 2 is used to contact a plurality of terminal mother lines of pixels arranged in the liquid crystal cell array glass substrate 3. π 宅 禾 π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π Each of the lines L1 and L2 is provided with a mineral tooth shape. Further, the probe 2 is extended such that the odd-numbered conductive needle-like body 11a protruding from the upper plurality of conductive needle-like bodies protrudes more upward than the even-numbered conductive needle-shaped body 11b. A step difference in height is formed in the protruding direction. The probe 2 is formed by connecting the conductive needles 11a and 11b on the upper side and the conductive needles on the lower side by a conductive coil spring 14. At the time of inspection, each of the conductive needle-shaped bodies 10 is in contact with each of a plurality of terminal conductive patterns 4 disposed in the pixels of the liquid crystal panel 3. Further, the upper insulating sheet 2 is superposed on the lower insulating sheet 13, and the long odd-numbered conductive needles 11a are contacted to contact the odd-numbered corresponding flexible substrates 5a attached to the bottom surface of the upper insulating sheet 12. The number-conducting conductive pattern 8 'the shorter even-numbered conductive needle-shaped body' 1b contacts the even-numbered signal-transferring conductive pattern attached to the even-numbered corresponding flexible substrate 5b of the lower surface of the lower insulating sheet 3 9. When the probe block 1 constructed as described above is used to constitute the inspection device for a liquid crystal panel, the overall structure thereof must include that the probe 2 and the terminal conductive pattern 4 should be disposed in the same number, for example, side by side. The required number 1 is made into a small single-turned probe block 1 having a width dimension (one block) substantially the same as the TAB in the support frame 21 (refer to FIG. 3), and will be connected to each other. The flexible substrates 5a and 5b of the needle block 1 are respectively connected to the odd-numbered corresponding address portion 6a of the patch panel 6 of the countable number and the even-numbered number, and the even-numbered corresponding address portion 6b, and The mating plate 6 is connected to the tester body 7. 315762 8 π In the conventional inspection apparatus for liquid crystal panel constructed as described above, the odd-numbered number of the conductive pattern 4 for the terminal and the two lines L1 and L2 of the two numbers are used for each of the lines. The distribution of the ore-like shape can sufficiently correspond to the narrow pitch of the conductive pattern 4 for the terminal. The line connecting the flexible substrate 5 and the mating plate 6 is divided into odd and even patterns, and The wiring 15 on the printed circuit board of the board 6 is connected, so that when the number of blocks of the conductive pattern 4 for the terminal is increased and the wirings 15 are in a state of being overlapped with each other, or each of the blocks of the pattern 4 is present. When the number of wirings increases, there is a problem that cannot be dealt with. Further, the problem that the wirings 15 are in a state of being in contact with each other can be solved by increasing the number of printed circuit boards constituting the mating plate 6, and drilling through holes, etc., to eliminate the wiring turns 5 of the respective layers, but Increasing the number of printed circuit board layers creates problems such as manufacturing difficulties, cost increases, and weight gain. Further, the mating plate 6 of the device is a multi-layer printed circuit board of 6 to 8 layers. Therefore, an object of the present invention is to provide an inspection apparatus for a liquid crystal panel, in which wiring is not increased by the number of laminated multilayer printed circuit boards constituting the adapter board, and the number of conductive pattern blocks for the terminal can be fully satisfied. This increases the 'or/and the number of wirings per block of the aforementioned pattern. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above problems.

The pad γ and the wiring 15 of the connectors C2 and C4 are connected to the pad 1 of the even-numbered address portion 6b. Further, the pad L is in contact with the probe body provided in the tester body 7 (see The probe body p) in Fig. 3 electrically connects the mating plate 6 and the tester body 7. In a continuous manner, the mating plate 6 includes: a plurality of pieces using the wiring 丨 5 and a suitable through hole h a multi-layer printed circuit board, and the connection of the top surface is provided with a benefit of Cl, C2, ..., and the address portion 6a, 6b is provided on the bottom surface of the liquid crystal panel. Since the flexible substrate 5 is divided into an odd number 5a and an even number 5b, the flexible substrates 5 (5 & 5b) have an intersection with each other, but there is no problem due to the intersection, and the odd number corresponds to the abundance substrate 5a. The connection end portions 5 A, 5B of the flexible substrate 5b corresponding to the even number gradually approach the odd-numbered corresponding address portion 6a, and the even number Should address portion 6b, it can be set to a very short connecting line 15 'to achieve the purpose of simplifying the wiring 15. 315762 14 1325499 Therefore, the mating plate 增加 is increased by the number of blocks corresponding to the conductive pattern 4 for the terminal, or/and the number of wires of each block of the aforementioned pattern 4 is increased. Further, since the adapter board 6 crosses the flexible boards 5, the adjustment steps of the conventional layer wirings 15 can be simplified, and accordingly, it can be constituted by a printed circuit board having a very small number of layers. For example, when the number of blocks of the terminal conductive pattern 4 of the array glass substrate 3 for a liquid crystal panel is eight, it is necessary to laminate 6 to 8 glass substrates to form the mating plate 6 in the conventional device. The mating plate 6' requires only two to four glass substrates to be laminated. As described above, according to the present invention, each probe block is divided into an odd-numbered corresponding flexible substrate and an even-numbered corresponding scratch according to the arrangement positions of the odd-numbered corresponding address portion and the even-numbered corresponding address portion in the mating plate. The substrate can be made extremely short by connecting the connection terminals of the odd-numbered corresponding flexible substrate and the even-numbered corresponding flexible substrate, the odd-numbered corresponding address portion, and the even-numbered corresponding address portion to avoid the intersection of the aforementioned connection wires. In the state of simplification, the number of layers of the multilayer printed circuit board constituting the adapter plate can be reduced, and the manufacturing can be facilitated, the weight of the device can be reduced, and the cost of the device can be reduced. In addition, there is also a portion in which the number of laminated sheets of the multilayer printed wiring board constituting the mating plate is small, an increase in the number of conductive pattern blocks for the terminal, or an increase in the number of wirings per block of the pattern. advantage. Further, it is easy to distinguish between the odd-numbered corresponding flexible substrate and the even-numbered corresponding flexible substrate by bending the respective flexible substrates. (Industrial Applicability) As described above, the inspection apparatus for a liquid crystal panel of the present invention has a state of a conductive pattern for a terminal of a flexible base 315762 1325499.
